| titleOfInvention | Method for leaching arsenic-containing gold concentrate and treating leachate of arsenic-containing gold concentrate |
| abstract | The invention relates to a processing method for leaching arsenic-containing gold concentrate and leachate thereof, which comprises the following steps: grinding the arsenic-containing gold concentrate, adding a reinforcer, mixing with alkali liquor, carrying out pressure leaching at 25-100 ℃, and carrying out solid-liquid separation after leaching is finished; adding lime milk into the leachate for reaction, performing solid-liquid separation, adding ferrite into the separated liquid for reaction, performing solid-liquid separation, adding lime milk into the separated liquid for reaction, performing solid-liquid separation, and introducing CO into the separated liquid 2 Or air, solid-liquid separation is carried out after full reaction, and the obtained separation liquid is returned to be used for leaching the arsenic-containing gold concentrate. The invention realizes the alkaline pressure leaching of the arsenic-containing gold concentrate at lower temperature, can reduce energy consumption and is beneficial to avoiding the generation of an intermediate product S simple substance at low temperature. In addition, through the improvement of the process, the method can effectively purify and recover the leaching solution, separate out a large amount of sulfate and arsenate generated in the alkali pressure leaching process, and is a clean production process. |
